Pranam Q2 The gaits of animals that walk or run bipedally, with human gaits, underwent a lot of research and found though the terminology BI PEDAL is a misnomer. The general conclusion is that no animal walks or runs as we do. We keep the trunk erect; in walking, our knees are almost straight at mid-stance; the forces our feet exert on the ground are very markedly two-peaked when we walk fast; and in walking and usually in running we strike the ground initially with the heel alone. No animal walks or runs like that. Q8 Density of the Earth is 5.52 grams per cubic centimeter. // Density refers to the amount of mass per unit volume, such as grams per cubic centimeter (g/cm3). The density of fresh water is 1 g/cm3 at 4o C but the addition of salts and other dissolved substances increases surface seawater density to between 1.02 and 1.03 g/cm3. The density of seawater can be increased by reducing its temperature, increasing its salinity, or increasing the pressure. Earth is lighter than sea?. Water is inside the earth and then why did not the earth float?. KR IRS 2722
